TENT-WINDOW.

Application filed July 6, 1908.

Specification of Letters Patent.

Patented May 18, 1909.

Serial No. &42,228.

To all whom it may concern:

Be it known that I, WILLIAM E. IVALsn, a citizen of the United States, residing at Morris, in the county of Grundy and State of Illinois. have invented certain new and useful Improvements in Tent-VVindows, of which the following is a specification.

The window of the present invention is designed with particular reference for use in connection with a so-called window tent adapted for use in the window of a room, although the window of the present invention is applicable for use in connection with tents generally.

The object of the invention is to provide a window of a flexible material, like transparent celluloid, which can be readily opened, closed or removed, and which, when 0 osed, will tightly seal the opening in the wall of the tent against the admission or escape of air, and which will also provide for the shedding of rain and prevent leakage of water through the tent orifice.

In window tents which are extensively used in the treatment of certain diseases and conditions of debility, it is desirable and important that the user of the tent be enabled to look therefrom into the room, and it is further desirable to provide an opening to which access may be had to the user whose head only is inserted within the window tent; and the present invention is devised with special reference to the conditions above named, and is so constructed that the win dow can be easily opened and closed as 00- casion may require.

The invention consists in the features of construction and combination of parts hereinafter described and claimed.

In the drawings, Figure 1 is an outside elevation of the tent wall, showing the-window closed; Fig. 2 an inside elevation of the same, showing the window closed, and showing, at the right hand side, a protective sheath or flap adapted to be used to seal the crack or opening around the window; Fig. 3 an outside elevation of the tent, showing the window opened; and Fig. 4 a sectional detail, showing the method of forming the window and frame.

The invention comprises a window 5 which is preferably in the form of a flexible transparent celluloid sheet, the edges of which are sewed into a canvas frame 6 of rectangular shape comprising a top strip 7, a bottom strip 8, and side strips 9, all of the strips being of double thickness of canvas. The to and bottom strips have entered along t eir edges a pair of flexible bars 1.0, preferably of steel, the ends 11 of which project laterally from the sides of the canvas window frame and furnish tongues for securing the window frame in position. In addition to the steel strips at the top and bottom, the canvas window frame is reinforced and properly distended by side strips 12, which are preferably in the form of thin flexible steel bars, the ends of which overlie the top and bottom flexible bars, all of the bars be ing suitably sewed into the canvas fabric of the frame. The window cooperates with a window opening 13 in the canvas tent wall 1 1, which opening is of substantially the same size as the transparent window, being less in size than the exterior dimensions of the window frame. Adjacent the o ening at the top are a pair of vertical top s its 15 of a size to have the top tongues 11 projected therethrough, and adjacent the bottom of the window opening are a similar pair of bottom slits 16, likewise of a size to have the bottom tongues projected therethrough. In order to reinforce the seam or crack, the window frame, on the inside and closely adjacent the inner edge of the frame, is provided with a flap 17 which is loose around its outer edge and is adapted to be suitably distended and pinned or otherwise secured to the inner face of the tent wall adjacent the opening therein, thus overlapping the seam and preventing ingress or egress of air.

In use, the window frame is inserted through the window opening, as shown in Fig. 1, thereby bringing the upper edge of the opening outside of the upper portion of the window frame, and bringing the lower edge of the window opening inside of the window frame. The opening in the tent wall, being normally of less width than the width of the frame, will be distended or drawn somewhat, as best shown in Fig. 1. After the window frame has been thus inserted in position, the upper ends 11 will be projected outwardly through the slits 15, and the lower ends 11 will be inwardly projected through the slits 16.

By arranging the window frame in the manner indicated, rain or other water will be carried down over the outside of the struc ture and no water will be admitted through the crack around the window frame. Where additional security is desired, the flap 17,

which is secured around the inner edge of the window frame and overlaps the oint or seam, can be outwardly distended to overlie the crack, which makes the window air tight as Well as water tight. In many cases, however, the fla will not be necessary, and it is not intender to limit the invention strictly to this feature.

When it is desirable to open the window, the upper tongues will be removed from the upper slits 15 and the window frame withdrawn from the opening and allowed to hang down, as shown in Fig. 3, being supported from the lower slit 16 only. Obviously the window frame can be bodily removed, if desired. When inserting and removing the window, it will be necessary to bend it considerably in order to properly position the lateral projecting tongues within the slits provided therefor, and this bending or manipulation can be easily performed by reason of the flexible character of the steel bars which comprise the support for the window frame.

In describing the invention I have used the term canvas since this is the fabric which will be ordinarily employed in many cases; but by the term canvas I mean to cover any suitable fabric or material which is capable of being used in the manner indicated. In like manner, in speaking of a flexible frame, I do not intend to be limited to one formed in the manner shown, since, obviously, the bars composing the frame might be connected together or formed of a continuous bar of metal without departing from the spirit of the invention.

W hat I regard as new and desire to secure by Letters Patent is:

1. In combination with a flexible tent wall provided with a window opening and having upper and lower slits adjacent the opening,

' r a window of flexible material inclosed within a flexible window frame having ears adapted. to be entered through the up er and lower slits, substantially as described? 2. In combination with a flexible tent wall provided with a window opening and having upper and lower slits adjacent the opening, a window of flexible material inclosed within a flexible window frame having ears adapted to be entered through the upper and lower slits, the Window frame being projected through the window opening to bring the upper edge of the o ening outside of the window frame and tie lower edge of the openin inside of the window frame, substantia ly as described.

3. In combination with .a flexible tent wall having a window opening therein and having slits adjacent the opening, a flexible window inclosed within a flexible window frame having upper and lower flexible bars entered through the window frame and outwardly projecting from the sides thereof to furnish tongues adapted to enter the upper and lower slits, substantially as described.

4. In combination with a flexible tent wall having a window opening therein and having slits adjacent the opening, a flexible window inclosed within a flexible window frame having upper and lower flexible bars entered through the window frame and outwardly projecting from the sides thereof to furnish tongues adapted to enter the upper and lower slits, the window frame being projected through the window opening to bring the upper edge of the opening outside of the window frame and the lower edge of the openin inside of the window frame, substantia ly as described.

5. In combination with a flexible tent wall having a window opening therein and having slits adjacent theopening, a flexible window inclosed within a flexible window frame having upper and lower flexible bars entered through the window frame and outwardly projecting from the sides thereof to furnish tongues adapted to enter the upper and lower slits, the window frame being -pro jected through the window opening to bring the upper edge of the opening outside of the window frame and the lower edge of the opening inside of the window frame, and a protective flap secured to the window frame near the inner edge thereof and adapted to overlie the crack between the frame and the window opening, substantially as described.

6. In combination with. a flexible tent wall provided with a window opening and having slits adjacent to the opening, a window of flexible material inclosed within a flexible" window frame provided with outwardly extending members adapted to be entered into the slits, substantially as described.

7. In combination with a flexible tent wall provided with a window openin a window of flexible material inclosed witi a flexible window frame, and fastening members adapted to be disengaged by bending or bowing the flexible window frame, and 7 adapted to be engaged by the straightening of the window frame, substantially as described.
